 The package holds only what every service can reuse. Anything a service owns is injected, never referenced.
 - **No site-specific content.** No page markup, no asset catalog, no `Bundle.module` lookups. What a type needs, it takes as a parameter: the `bundle:` whose String Catalog names the supported languages, the `document:` closure that builds a page for a locale, a `Page` conformer's `metadata` and its optional head concerns (`summary`, `canonicalURL`, `socialCard`, `structuredData`, `analytics`). URLs arrive absolute and fully formed — composing them stays with the page.
 - **Types own their format; `Page` renders generically.** Each head concern derives its own render-ready form — `SocialCard.tags`, `StructuredData.payload`, `Analytics.attributes` — which `Page` applies without knowing the vocabulary. A page's `scripts` and the tracker render as `defer`red head tags, the tracker preceded by a `preconnect` to its cross-origin host.
+- **Nodes are joined by `@id`, not repetition.** A node another page must point at gets its identifier from a helper rather than a hand-spelled fragment — `organizationID(forSiteURL:)` names the node the site-wide initializer builds, and that initializer's `founder` takes such an identifier back. A service adds the helper for any node it owns, so neither side can drift.
 - **Services fill the gaps once, via extensions.** A service restores its convenient call sites retroactively — the Website's `*+Defaults` are the pattern. The open schema.org vocabularies work the same way: the package declares the shared `Property.Name` and `Node.Kind` constants, a service adds its own.
 - **Method structs.** Single-operation types such as `FingerprintAssets` take lifetime-fixed configuration in `init` and per-call inputs in `callAsFunction`.
